Screen centering in interlace mode seems to be correct in 60Hz but in 50Hz there's a big downwards shift. You can test it with this thing I made a while ago : http://www.tmeeco.eu/BitShit/XMAS2K9.BIN Is there means to change region on the fly ? It would be a nice feature, especially since there seem...

Pinouts differ (VCC is in a totally different place), with a small modification those things could be used. No idea how hostile the protocol is, it might be better idea to just make your own adaptor and have existing Sega mice compatibility there, far more useful for most people I imagine.

I have an extra tidbit about the offsetting problem. it seems to happen in 50Hz+interlacing, one of interlace mode demos produces same kind of shift of the image as the menu ROM. 1:1 pixel option with zoom is probably best way to go about it. Another interesting thing would be to option have blankin...

The menu ROM seems to display the image with an offset (slightly to right, a lot towards bottom, OS mouse cursor shows the extend of the offsetting) : http://www.tmeeco.eu/BitShit/Temp/IMG_0008.jpg And when I run a ROM I get "Failed to lock texture: LockRect(): INVALIDCALL" message, after which thin...

At least as far as of consoles go, the "theory" is wrong on every count if you are going for authentic mockups: the MD, for example, renders 320- and 256-pixel wide lines with the same physical lenght: they images produced have the same physical aspect ratio, even though they have different logical...

I suppose the most important thing is that the RGB color levels are not linear. This thread has all the relevant info about the video output : http://gendev.spritesmind.net/forum/viewtopic.php?f=22&t=2188 Unlike 8 bit consoles, there is not a fixed number of unique tiles that can be used, as you can...

When MCD is connected the 400000...7FFFFF range will have MCD BIOS and other bits of it visible there. When you disable the check stuff will probably run but sooner or later there will be hardware damage due to bus fighting that happens betwees MCD and the everdrive cart. Cart side tends to win over...

There is no mirroring effect going on when the width is 64 tiles, only the first 32 rows get used, when the width is 32 tiles it does produce the mirroring effect, 0...31, 0...31, 64...95, 64...95. EDIT : I tested out all combinations : H V 00 00 - 32x32 00 01 - 32x64 00 10 - See above 00 11 - 32x12...
